Creating an Author Index

I have created a bibliography using endnote, but I would like to add an author index as well. I would like it to reflect each page on which an author is cited, for example:

Adams, A. S. …34,45,78
Beaver, R. T. …76,98,99
Carter, H. Y. …23,43,65

This would pay for the cost of endnote several times over.
